Short-term neonatal outcomes in diamniotic twin pregnancies delivered after 32 weeks and indications of late preterm deliveries.

Objective: We sought to compare neonatal outcomes in twin pregnancies following moderately preterm birth (MPTB), late preterm birth (LPTB), and term birth and determine the indications of LPTB.

Study Design: We performed a retrospective cohort study. MPTB was defined as delivery between 32(0/7) and 33(6/7) weeks and LPTB between 34(0/7) and 36(6/7) weeks.

Efficacy of the genetic sonogram in a stepwise sequential protocol for down syndrome screening.

Objectives: The purpose of this study was to evaluate the efficacy of the genetic sonogram in Down syndrome screening for women who have received the stepwise sequential test.

Methods: This retrospective cohort study included women with singleton pregnancies who underwent stepwise sequential (first-trimester combined and second-trimester serum) screening and then had a genetic sonogram between March 2005 and January 2010. Stepwise sequential Down syndrome risks were multiplied by either a positive or negative likelihood ratio based on the second-trimester sonographic findings to determine the final Down syndrome risk.

Perinatal outcomes based on the institute of medicine guidelines for weight gain in twin pregnancies.

Objective: To estimate the impact of the Institute of Medicine's (IOM) weight gain recommendations on perinatal outcomes in twin pregnancies.

Methods: In this multicenter cohort study, using the 2009 IOM guidelines, we examined pregnancy outcomes in 570 uncomplicated diamniotic twin pregnancies. Subjects were grouped according to pre-pregnancy body mass index.

Nuchal translucency and cardiac abnormalities in euploid singleton pregnancies.

Objective: To investigate different cut-off levels of nuchal translucency (NT) to predict abnormal cardiac findings (ACF) in second trimester ultrasound examination and confirmed postnatal congenital heart defects (CHD) in euploid pregnancies.

Methods: A retrospective analysis was performed on singleton pregnancies examined in our ultrasound units from 2006 to 2011. Fetuses with an abnormal karyotype were excluded.

Fetal hydronephrosis as a predictor of neonatal urologic outcomes.

Objectives: The ability to predict surgically relevant fetal renal hydronephrosis is limited. We sought to determine the most efficacious second- and third-trimester fetal renal pelvis anteroposterior diameter cutoffs to predict the need for postnatal surgery.

Methods: We retrospectively reviewed the medical records of mothers and neonates who had a prenatal sonographic examination in our Perinatal-Pediatric Urology Clinic and received follow-up care.

A case report of human granulocytic anaplasmosis (ehrlichiosis) in pregnancy and a literature review of tick-borne diseases in the United States during pregnancy.

Unlabelled: There is paucity of data regarding tick-borne diseases during pregnancy. Here, we report a case of human granulocytic anaplasmosis during pregnancy with successful treatment and a favorable neonatal outcome. We also review diagnosis, treatment, and outcomes of published case reports from 1983 to 2010 of human granulocytic anaplasmosis, Lyme disease, babesiosis, and human monocytic ehrlichiosis in the United States.

Laparoscopic management of chemical peritonitis caused by dermoid cyst spillage.

Background: Dermoid cyst is the most frequent benign ovarian tumor. Spillage of cyst contents during surgery is common and can rarely lead to chemical peritonitis.

Case Report: A patient presented 3 days after attempted laparoscopic removal of bilateral dermoid cysts.
